Bluetooth low energy Characteristics, a beginner's tutorial

[Nahom]

Hi Martin, I follow all the steps in your tutorial(Bluetooth low energy Characteristics, a beginner's tutorial) and I am able to create the characteristics and the notification(CCCD). Unfortunately when I tried to read the temperature value from the sensor. it is not working. After I Click "Toggle notifications" the characteristic value isn't updated every second even I don't see LED 4 and the value line in nRF Connect is not blinking green every second. I double check all the steps I did it the same way as you stated in the tutorial but still, it isn't working. when I click "Toggle notification" it gives me a value 0x01 in nRF Connect line but it should change with the value of the temperature but it is not.

Hi Nahom, 

Have you made sure you based your application on SDK v15.0 ? 

Please take a screenshot of NRFConnect app after you enable notification. 

Have you tried to use the file inside "Solution" folde on github? And compare it to your implementation.
